Light micrograph of a MEMS (MicroElectroMechanical System) microphone, installed in nearly all modern smartphones. The image shows the MEMS microphone with disassembled housing to show the wafer components inside. For dimension comparison a match head was captured together with the microphone unit. Microscopic contrast technique: Incident darkfield together with incident brightfield. Magnification: 30x when printed 10 centimetres wide.
